#44 Ctrl-Z in relations gets exception...

[Eric D. Pancoast]

From Annotator (Sanipa):

When I mistagged a relation, to undo this, I accidentally hit "ctrl-z"
instead of "crtl-d" and an out of bounds error message popped up
(see OutofBoundsException.gif). This time, I remembered to press
the "stack trace" button so that you can see the stack trace
messages for it to debug it (see StackTraceForOutofBounds.gif)
